Mate yes, old farmhouse I stayed at in the Cheviots a few years back, three nights running at dead on 3am something was going at the walls like it had a schedule to keep. Turned out to be a pipe apparently but honestly the timing was too precise for me to fully buy that explanation.
The 3am thing is what gets me though, that hour keeps coming up in these stories and I don't think thats coincidence. Some people call it the witching hour, others reckon its when the veil between whatever and here is thinnest. Either way my pipe has never once knocked at 2:47 or 3:14, always bang on the hour.
Anyone else notice the timing is always suspiciously neat? Feels like whatever it is has read the same paranormal rulebook we have.
